HELP regarding Upgrade to MM STOCK ROM OR CM 13.0 !!! - Zenfone 2 Laser Q&A, Help & Troubleshooting

Hi guys, its been a few days since I joined here. [Read : I am a noob/newbie in Android related things, and I desperately need help.]
In July (maybe, I forgot), I rooted my ZE550KL, using exactly this method from the website of www-asus-zenfone-com. :cyclops:
Now that, my android seems aged, I wanna shift/upgrade to Marshmallow/Nougat, be it Stock or Custom ROM.
Few days earlier, I unlocked my Bootloader using the Unofficial Bootloader Unlocking Method, as found on this Forum.
I also installed TWRP Recovery, and I tried to flash CM-14.1 [7.1] Nougat-Nightly through TWRP, but, unfortunately, resulted in Status 7 Error. I tried to solve the problem by removing "asserts" section in Update-Binary text file, in the build. But, again, I seemingly worsened the problem; as I got Status 6 error thereby. So, I did factory reset, and I still retain root.
Now, today as I am going through the Official thread of CM 14.1 Nougat, I saw numerous users reporting Bugs of connection issues (something like Wifi to Mobile Data switch problem), which I would like to OBVIOUSLY AVOID, as I want a stable, bug-less build. So, I am thinking to go with the last snapshot build of CM 13.0 Marshmallow.
Here comes the my question : " SHOULD I FLASH CM 13.0 MM -- OR -- STOCK ROM OF MM -- OR -- RESURRECTION REMIX MM ROM?? "
In any of the case, please guide me through the process of doing so.
And, if I have to flash CM 13.0 MM, what would I do if I encounter Status Error 7 again ? :crying:

first you have to upgrade it to marshmallow using stock rom. Then you can flash cm13 or cm14.1

While flashing CM13 if that error 7 includes "asus.verify trustzone failed..." Then its bcoz of need to update modem files (LP to MM)....
Easy way to overcome it is..... download MM modem ZIP from second post of OFFICIAL CM13 thread (120MB) and flash it using TWRP (If you are using twrp).... THEN you can flash cm13 hopefully without error 7....
If you are using stock recovery then Either u can flash twrp and use above method... OR... Download ASUS ZE550KL firmware zip file from ASUS site (1.6GB) .... Put it in SDCARD... Then boot to stock recovery and use "apply update from sdcard" option... select ZIP... Alongwith firmware Ur Modem files will also update to MM... and now u can flash twrp and then cm13...
sorry.. I know if i am lazy to post direct links...
Try it.. I will help if i can

We have both stable RR and CM13.
CM is simple and clean and less loaded.... RR is most feature rich Custom rom we have alongwith stability...
Rest depends on what type of user, u are... If u like trying differnt ROMs... Start with CM13...
If u just want to have a feature rich longtime setup, U can use RR directly without wasting time... It is based on CM, So it obviously have everything CM has.... :good:

It's because you are flashing MM rom (except cm13) and you are on Lollipop or vice versa.

Possible problems,
- the rom is not for your device or variant
- The bootloader is for another version of Android
- Twrp was compiled with a different version of Android so are you going to get an error.
- Your bad luck exceeds an acceptable level ... ???

You get green screen when:
1) You flash MM ROMs (based on stock Touchwiz MM) over Lollipop and vice versa.
2) You flash MM/N ROMs (based on AOSP/CM such as LOS13, AOSIP, Mokee etc.) over Lollipop and vice versa.
3) I can't confirm this, but based on your comment, you get green screen when you flash a MM kernel over Lollipop and of course, vice versa too.

For those, who -as I did - don't really understand this (see the quote)...
I had the same issue when I wanted to install a custom Marshmallow ROM (6.0.1) over my stock Lollipop (5.1.1). The solution was to download and flash a new Bootloader and Modem with Odin. See tis:
https://forum.xda-developers.com/galaxy-j5/how-to/6-0-1-5-1-1-bootloader-modem-j500xx-t3566801
I just ran into this error while trying to install a custom ROM for my J500H.
My phone was running latest 6.0.1. I installed TWRP from This thread, then installed followed the instructions to install Resurrection Remix (7.1.2), but on first boot i got the green screen with the error (set warranty bit: kernel). Also tried Lineage 14.0 but doesn't work. I can still enter TWRP and download mode after getting this error.
This is my first time flashing a Samsung device. Could someone tell me what i did wrong?

Sorry, first time i didn't your post till the end.
First of all.
Restore firmware with "Samsung smart switch".
You can downgrade to 5.1.1 by this instruction.
1.Flash this firmware by Odin
https://drive.google.com/file/d/0B-pt1IG7T4hmVzhuMnRyeTBjTGM/view?usp=drivesdk
(Before flashing, wipe all storages(all except internal, external in advanced wipe. If you have stock recovery, you must do both wipes)
2. After first boot flash recovery from Vince
(for both bootloaders)
3. Before flashing RR5.8.4 wipe all storages too( all, except extrnl and intrlnl)
4. Flash RR and gapps.
5. Wipe data and cache.

KTLEDUOS SM-G900FD Lineageos 14.1 Builds 080217 - 080917

Hi there,
just to give a feedback. DUALSIM is not working on both builds. LTE function fails. Made complete new flash, nothing helps...
Same applies to crDroid - build 20170802 - 7.1.2
I would kindly ask for help around here
Thanks,
Light of Magic
after one day....
Hi,
I don´t know why dualsim function stopped working... I tried 2 builds each - Lineageos, Ressurection OS, crDroid ... going back to stock ROM, everthing works fine. I even searched through the net to get a suitable pit file.
Only thing - I wanted to update like https://forum.xda-developers.com/galaxy-s5/development/rom-lineage-os-samsung-galaxy-s5-lte-t3534283
And I could not find TWRP 3.0.0 as recommended, so I use 3.1.0 - I could not install SkiesROM, since it was maybe to large....
For any help I would be greatful,
Light of Magic

Here u get TWRP 3.0.0.0 for klte as recommended. Extract the zip before use. Use the .tar for Odin flash or the .img for flash through recovery. Tip: download twrp-app from Playstore. You'll find all downloadable content there.
I've read that going back from LOS / AOSP to SkiesROM is not possible without flashing a Stock Rom first. Make sure u have flashed the fitting bootloaders via Odin before u flash the Stock ROM. Suitable are the ROMS from ALEXNDR. They're prerooted and a good base to go further.
Good luck
still
I wounder, does anyone have the same issue? Using the builds in May I did not have this issue.
Thanks to ottili81 for TWRP 3.0.0.0 !!!

What im trying to tell is that my problem is not only installation in custom roms but i also cant install any other roms eiether from official site or some other site which means i cant install any roms accept the one the stock rom i mentioned above. And also i already tried to install MM firmware but it gives out error code 7 in twrp. I tried as i was said to install the previous version of lollipop before the update of MM came out but still i cant install them.

Which Android u r using now
Lolipop or MM
is your bootloader locked on unlocked?
just go back to stock versions for now
if u r on lollipop, download the 'next version' from asus
if u r on marshmallow, download the next version from asus
use fastboot (bootloader) mode to flash if required
when all is stable and done,
download & flash twrp
flash lineage 13, then lineage 14

Again thank you so much for ur help

not able to flash twrp

Hi guys I have rooted my YU yureka cm 11. Its been 2 days I am trying to flash twrp on my device using both twrp official app and twrp manager. I have tried 3.1,3.0,3.02 versions while flashing. After flashing it says successfull but when I tried to reboot into recovery the mobile stucks on YU logo I think gets bricked this is what happening every time
CM11?
Any reason to sticking with CM11?
It is a 32 bit ROM and TWRP you're trying to flash is 64 bit. It won't get flashed ever.
Better install COS12.1 or any other custom ROMs.
There is no any specific reason for sticking with cm11 I thought it is most stable.
So is there any way I can flash twrp?
Or do I have to upgrade to cm 12.1 and then try to flash?
Can you recommend me any rom with better stability for yureka?
First try to upgrade to COS12.1 and than flash TWRP.
There are lots of N custom ROMs available and is stable. You can find more about them here or at YU Forum.

Flash Cos12.1 via fastboot, as it will change ur architecture from 32bit to 64bit...
Then check bootloader status, and if locked, unlock it as well, flash TWRP and enjoy custom ROMs,
Nougat ROMs are much stable now
For any problem, feel free to ask,
Thank YOU
thanks
Thank you very much guys , your help is very very appreciated.

FingerPrint Enrollment not working on any Custom Rom

The fingerprint was working fine on stock rom. Unlocked the bootloader and flashed twrp image. Somehow I formatted the internal storage erasing everything. After that, I flashed Pixel Experience custom rom and the fingerprint scanner isn't working. Getting "fingerprint enrollment issue". The enrollment happens only when I try pressing it very hard and I didn't face the issue on stock rom. I tried every custom rom available my bad. Somehow registered the edge of the finger and its working for now. What is the issue, I don't think it is hardware issue Any fixes for the same?

By any chance were you on the Oreo soak test when last on Stock rom? If so, the blobs wouldn't be compatible. Confirm whether or not that was the case, and if it is, then I'll point you in the right direction.

Taken from the Oreo thread:
Important information if downgrading to Nougat and Custom Oreo roms
The Oreo roms will change the ownership of specific files and folders in the /persist folder. As a result of this, stock Nougat will have issues such as lost IMEI, no Volte, no 4G, etc. In order to overcome these issues, either follow the instructions in the link above, or flash the following zip in TWRP.
potter-stock-persist-fix.zip
Another potential issue is that, as a result of various partitions being updated, the new Oreo blobs may not be compatible with existing Nougat roms (stock or custom), or even current Custom Oreo roms. This may result in issues such as the fingerprint reader not working, etc. To ensure they run correctly, it is MANDATORY to install one of the latest Stock Nougat TWRP flashables. This will ensure that all affected partitions are compatible with Stock Nougat and Custom Oreo roms. You can get these from this thread here:
[Nougat][Stock][Rom] TWRP Flashable Stock Builds
So flash the persist fix from the first link, and flash the latest Nougat stock rom from the second. Reboot and make sure all is working OK in stock. Then flash whichever custom rom you want.

Step by step instructions are in my post above... Do you have a more specific question?
Does this work with moto G5s plus [sanders]
Will the above method work with moto g5s plus sanders

Yes, if you did the same thing, i.e. flashed stock Oreo and then went to an Oreo custom rom, then yes the same approach will work. I have a flashable build and persist fix for sanders here:

Clean flash/Dirty flash?
@NZedPred I am facing the same problem. I own the Indian Moto G5 Plus (retin)
Here's what I did -
1. I unlocked my bootloader
2. I updated to Oreo (soak test) using the OTA capture.
2. I somehow rooted my phone after flashing TWRP.
3. Just after I flashed TWRP i.e. before rooting, I took a complete backup including the persist and EFS partitions.
4. After rooting, I clean installed MSM-Xtended ROM (8.1.0)
5. Everything is fine, but the fingerprint feature doesn't work/appear anywhere. Even the gesture support is gone.
What do I need to do?
If I follow your steps mentioned above i.e. flashing the persist-fix first, flashing the Nougat ROM you provided and then flashing any custom ROM, how should I proceed?
I am really confused whether I should clean flash (Wipe Data, System, Cache) after every step or dirty flash everything.
Please guide me.
Before you go back to custom ROM from stock Oreo ROM you have to flash stock nouget ROM if not fingerprint , NFC will not work.

Taken from the Oreo thread:
Important information if downgrading to Nougat and Custom Oreo roms
The Oreo roms will change the ownership of specific files and folders in the /persist folder. As a result of this, stock Nougat will have issues such as lost IMEI, no Volte, no 4G, etc. In order to overcome these issues, either follow the instructions in the link above, or flash the following zip in TWRP.
potter-stock-persist-fix.zip
Another potential issue is that, as a result of various partitions being updated, the new Oreo blobs may not be compatible with existing Nougat roms (stock or custom), or even current Custom Oreo roms. This may result in issues such as the fingerprint reader not working, etc. To ensure they run correctly, it is MANDATORY to install one of the latest Stock Nougat TWRP flashables. This will ensure that all affected partitions are compatible with Stock Nougat and Custom Oreo roms. You can get these from this thread here:
[Nougat][Stock][Rom] TWRP Flashable Stock Builds
So flash the persist fix from the first link, and flash the latest Nougat stock rom from the second. Reboot and make sure all is working OK in stock. Then flash whichever custom rom you want.

I was also in the same problem of fingerprint not working. Tried your method i.e. flashed persist zip and nougat rom (after wiping dalvik, system ,data, cache) and now when I try to clean flash custom Oreo rom . Gapps is not getting flashed . Its detecting the rom as 7.1.2. any solution for this

can you please guide me to install a custom oreo rom. because when i try to flash custom oreo rom (franken rom i used) , the rom gets flashed but the gapps (arm64 mini 8.1.x) fails everytime and shows error code 20 (incompatible rom). but i had flashed both the rom and the gapps successfully before the fingerprint issue bcoz of which i had to flash the stock 7.0 with the persist fix. and one more thing the rom is getting flashed succesfully (as twrp shows me) but when i try to boot into system without the gapps installed( i.e. only with the rom) it gets stuck on the bootloader page so i think the rom itself is not getting flashed. please help......
